When does spermarche usually occur?

• A. At birth.
• B. One year after accelerated penis growth.
• C. At age 5.
• D. After menarche.

Answer: (B)

Spermarche is the first ejaculation and signals that puberty has progressed to a new stage in males. In typical development, puberty starts with the testes enlarging, followed by a rapid growth phase of the penis. The first ejaculation usually occurs about a year after that accelerated penis growth begins. So the timing described—one year after accelerated penis growth—is the best fit for when spermarche tends to happen. It isn’t at birth or around age five because those are prepubertal times, and it isn’t tied to female events like menarche, which is the first menstruation in girls.
